Answer
5
Step-by-step explanation:
8n+10=50
-10 -10
8n=40
8n/8 = 40/8
n= 5
She will be able to buy 5.
DOUBLE CHECK:
8(5)+10=50
40+10=50
50=50
Answer:
I think it would be 120
Step-by-step explanation:
You add 120+120 and it would equal 240. Then 240 dived by 2 which will equal 120.

The amount he needs to pay is $ 28753.61.
Step-by-step explanation:
Given,
Principal (P) = $ 8000
Time (T) = 10 years
Rate of interest (R) = 13%
The payment will be quarterly so, n = 4
To find the amount of compound interest.
Formula
Amount = 
Now,
Putting the values of P, T, n and R we get,
Amount = 8000(
= 28753.61 (approx)
